Built-in Heat Diffusion Lamp Body for LED Lamp

Abstract

A built in beat diffusion lamp body for LED lamp was invented. The purpose of the invention is to solve the difficulties of poor heat conduction and diffusion caused by the small heat diffusion surface of the material of a conventional LED lamp. The lamp body is made of a set of heat diffusion vanes encircling the heat diffusion complex. The vanes and heat diffusion complex are made from Aluminum alloy in a single process of extrusion moulding. The transverse section of the heat diffusion body is volute shaped. The bottom of the heat diffusion complex is fixed to an aluminum board or an aluminum circuit: board by interference fit. The heat generated by the LED elements can be absorbed and diffused by the board, the heat diffusion complex and the surrounding diffusion element. The outward appearance of the heat diffusion lamp body may be shaped into cup, ladder, or cylinder likeness to satisfy the application requirement. The advantages of current invention are: efficient heat absorption, conduction, and diffusion, low cost for manufacturing, and aesthetic appearance.
